Marshal of the Royal Air Force (MRAF) is the highest rank in the Royal Air Force (RAF). In peacetime it was granted to RAF officers in the appointment of Chief of the Defence Staff (CDS), and to retired Chiefs of the Air Staff (CAS), who were promoted to it on their last day of service. While surviving Marshals of the RAF retain the rank for life, the highest rank to which officers on active service are promoted is now air chief marshal. Although general promotions to Marshal of the Royal Air Force have been discontinued since the British defence cuts of the 1990s, further promotions to the rank may still be made in wartime, for members of the Royal Family and certain very senior RAF air officers in peacetime at the discretion of the monarch; all such promotions in peacetime are only honorary, however. In 2012, the then Prince of Wales was promoted to the rank in recognition of his support for his mother, Queen Elizabeth II, in her capacity as head of the armed forces (commander-in-chief), while in 2014 Lord Stirrup, who had served as Chief of the Air Staff and Chief of the Defence Staff for over seven years, was also promoted.
Flying officer is a junior commissioned rank in the Royal Air Force (RAF) and the air forces of many countries which have historical British influence. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. In these cases a flying officer usually ranks above pilot officer and immediately below flight lieutenant.
Squadron leader is a commissioned rank in the Royal Air Force and the air forces of many countries which have historical British influence. It is also sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure.
Wing commander is a senior commissioned rank in the British Royal Air Force and air forces of many countries which have historical British influence, including many Commonwealth countries but not including Canada and South Africa. It is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. It ranks immediately above squadron leader and immediately below group captain.
Group captain is a senior commissioned rank in the Royal Air Force, where it originated, as well as the air forces of many countries that have historical British influence. It is sometimes used as the English translation of an equivalent rank in countries which have a non-British air force-specific rank structure. Group captain has a NATO rank code of OF-5, meaning that it ranks above wing commander and immediately below air commodore, and is the equivalent of the rank of captain in the navy and of the rank of colonel in other services.
Air commodore is a senior rank in the air forces of the United Kingdom and other countries including Australia, New Zealand, India, Pakistan and Zimbabwe. It is a one-star rank and is an air officer rank. It originated in, and continues to be used by the Royal Air Force.
Air Vice-Marshal (AVM) is a two-star air officer rank which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure.
Air marshal is an air-officer rank which originated within the Royal Air Force. The rank is used by the air forces of many countries which have historical British influence, including many Commonwealth nations. The rank is usually equivalent to a vice admiral or a lieutenant general.
Air chief marshal is a high-ranking air officer originating from the Royal Air Force. The rank is used by air forces of many countries that have historical British influence. An air chief marshal is equivalent to an Admiral in a navy or a full general in an army or other nations' air forces.
Flight lieutenant is a junior commissioned rank in air forces that use the Royal Air Force (RAF) system of ranks, especially in Commonwealth countries. It has a NATO rank code of OF-2. Flight lieutenant is abbreviated as Flt Lt in the Indian Air Force (IAF) and RAF, and as FLTLT in the Pakistan Air Force (PAF), Royal Australian Air Force (RAAF) and Royal New Zealand Air Force (RNZAF) and has sometimes also been abbreviated as F/L in many services; it has never been correctly abbreviated as "lieutenant". A flight lieutenant ranks above flying officer and below a squadron leader and is sometimes used as an English language translation of a similar rank in non-English-speaking countries.
Pilot officer is the lowest commissioned rank in the Royal Air Force and the air forces of many other Commonwealth countries. It ranks immediately below flying officer.
Officer Cadet is a rank held by military cadets during their training to become commissioned officers. In the United Kingdom, the rank is also used by members of University Royal Naval Units, University Officer Training Corps and University Air Squadron; however, these are not trainee officers with many not choosing a career in the armed forces.
Marshal of the air force or marshal of the air is a five-star rank and an English-language term for the most senior rank in some air forces. It is usually the direct equivalent of a general of the air force in other air forces, a field marshal or general of the army in many armies, or a naval admiral of the fleet.
The officer ranks of the Royal Air Force, as they are today, were introduced in 1919. Prior to that Army ranks were used.
The rank structure of the Royal Australian Air Force (RAAF) has been inherited from the Royal Air Force (RAF). The RAF based its officer ranks on the Royal Navy, and its airmen ranks on the British Army.
A five-star rank is the highest military rank in many countries. The rank is that of the most senior operational military commanders, and within NATO's standard rank scale it is designated by the code OF-10. Not all armed forces have such a rank, and in those that do the actual insignia of the five-star ranks may not contain five stars. For example: the insignia for the French OF-10 rank maréchal de France contains seven stars; the insignia for the Portuguese marechal contains four gold stars. The stars used on the various Commonwealth of Nations rank insignias are sometimes colloquially referred to as pips, but in fact either are stars of the orders of the Garter, Thistle or Bath or are Eversleigh stars, depending on the wearer's original regiment or corps, and are used in combination with other heraldic items, such as batons, crowns, swords or maple leaves.
The Australian Defence Force's (ADF) ranks of officers and enlisted personnel in each of its three service branches of the Royal Australian Navy (RAN), the Australian Army, and the Royal Australian Air Force (RAAF) inherited their rank structures from their British counterparts. The insignia used to identify these ranks are also generally similar to those used in the British Armed Forces.
Air chief marshal is the highest active rank of the Royal Australian Air Force and was created as a direct equivalent of the British Royal Air Force rank of air chief marshal. It is also considered a four-star rank. The only time the rank is held is when the Chief of the Defence Force is an Air Force officer.
Air marshal is the second-highest active rank of the Royal Australian Air Force and was created as a direct equivalent of the British Royal Air Force rank of air marshal, it is also considered a three-star rank. The rank is held by the Chief of Air Force (CAF), and when the Vice Chief of the Defence Force (VCDF), the Chief of Joint Operations (CJOPS) and/or the Chief of the Capability Development executive (CCDE) are Air Force officers.
Air vice-marshal is the third highest active rank of the Royal Australian Air Force and was created as a direct equivalent of the British Royal Air Force rank of air vice-marshal. It is also considered a two-star rank. The Australian Air Corps adopted the RAF rank system on 9 November 1920 and this usage was continued by its successor, the Royal Australian Air Force.
